flywheel resurfacing - please offer input
Shaggie
just called the local machine shop and told them I have a 180mm
flywheel that needs to be resurfaced. "No problem," they tell me.
They say they do it all the time. I say "OK, you do both the surface
where the clutch disc contacts the flywheel AND the surface where the
pressure plate bolts to, right? "Yes, sir. That needs to be done to
keep the clutch disk geometry relative to the flywheel in the correct
blah blah blah." or something like that. Like they know the deal.
"OK, cool" I say... "I've been told that the surface that the clutch
disk comes into contact with on the flywheel is not 100% flat, but
rather it's bevelled so that when the clutch disc contacts it, it
doesn't contact it 'all at once'... Have you heard of that before, or
do you just machine it flat?" He tells me he's never heard of that
before, that they just machine both surfaces flat, and that he does
this all of the time. Someone on ramva (I think I remember who it was
but I'm not positive) told me about the bevelled flywheel surface.
Can I get several confirmations or denials of this? I don't want to
pay someone $30 to trash my flywheel... I'd really appreciate y'all
chiming in here to let me know if there is a bevell and if so how
critical is it to have it re-machined that way. The guy on the phone
at the machine shop really *sounded* like he knew what he was talking
about, but then again...maybe I sounded that way to him too...if'n ya
know whut I mean. Yuk yuk! :-/

i've never heard of beveling the surface

For what its worth, I'll never heard of it.

surface 1mm DEEPER than before, in relation to the disc surface.. it
would make the stock pressure plate apply more pressure to the disc..
=more grip
Ask them about it and tell em you need a bit more clutch

it has changed, due to improved machery over the years, the final goal is
still the same FLAT, never heard of beveling that you mentioned. The pressure
plate is flat so you would want the flywheel the same way so that when the disc
is squeezed between the two there is a good match. Hope this helps.

That is not to say that it is correct or incorrect.
Somewhere in my dogged background I have had some dealings
with this very thought....................I'd not call the
surface bevelled, rather slightly , as in very slightly
different thickness from center to outside diameter of the
*grip surface*
Now,............I have been digging to try and find some
info on the subject, and can;t for the life of me find
anything that confirms my original post that mentioned such
a mild difference.
I am sad to say, I could very well be very wrong, but this
is something that keeps naggin at me and has for some five
or more years since right after acquiring my "daily driver".
I was kinda hoping for some support here, but I believe I am
outnumbered by a few already.
Now having said that, I gotta tell ya Shag, I am almost 100%
positive that my memory has the facts on this straight, I
just haven't been able to find anything remotely
substatiating.
Sorry if I misinformed.( hope I didn;t)

to bring my flywheel by the machine shop tomorrow to have them
resurface it. They say they can do it while I wait, so hopefully this
weekend I'll get everything put back together and the clutch will be
free of its chattering problem. Of course I'll take pictures of my
trials and tribulations with it... :-/

I think one of Berg's writeups mentions machining the pressure plate
flat, rather than the very slight taper that is "normal" on them.
IIRC, I took a straightedge to one and discovered that they are indeed
very slightly conical such that the central part contacts first. I
believe this was to give smoother clutch engagment.
It's been a long time since I checked this. Can anyone else confirm?

Never cut a flywheel any more than you have to, like a brake rotor,
once the metal is gone so is the flywheel, reminds me of a Camaro I
did, cut it trying to save money, clutch wouldn't fully dissengauge,
couldn't put it first or reverse, I need to learn to spell better, but
you get the idea.

Hey, at least you spelled *Camaro* right. Most posters don't.

scribbled this interesting note:
I could go out and check on the NOS 36hp flywheel I've got in the
garage, but that would mean finding it first!:~) If I run across it in
the next day or two I'll look it over close and get back with the
group.
